WHIP-LOCK.

Specification of Letters Patent.

Patented July 26, 1910.

Application filed May 18, 1910. Serial No. 561,952.

To all whom it may concern:

Be it known that 1, JAMES E. DUFFY, a citizen of the United States,residing at Chicage, in the county of'Cook and State of. Illinois, haveinvented new and useful Improvements in VVhip-Locks, of which thefollowing is a specification.

This invention relates to whip locks, the object being to provide a Whipsocket with a locking device whereby the whip may be readily locked inplace in the whip socket so that unauthorized persons will not be ableto remove the whip, at least without the exercise of a great deal ofskill and manipulation in breaking the lock.

To such ends this invention consists in certain novel features ofconstruction and arrangement, a description of which will be found inthe following specification and the essential features ofwhich will bemore definitely pointed out in the claims appended hereto.

The invention is clearly illustrated in the drawing furnished herewith,in which- Figure 1 is a central longitudinal section through a whipsocket showing in front elevation, my locking device and a fragment of awhip secured in the socket by means of said locking device, Fig. 2 is acentral longitudinal section of the whip socket taken on the line 22 ofFig. 1 and showing the locking device in side elevation and the whip ina position about to be connected with the locking device, Fig. 3 is ahorizon tal section on the line 33 of Fig. land Fig. 4 is a centrallongitudinal section through a fragment of a whip socket showing in sideelevation a fragment of a whip and whip lock in a slightly modifiedform.

Referring to the drawings, an ordinary whip socket A, will be seen whichis tubular in form having a closed bottom a. A frag ment of a whip B, isshown as secured in the socket by means of my improved locking device C.In the preferred form said locking device comprises a curved plate 10,secured in the whip socket and a pin or stud 11, secured to the lowerend of the whip stock and adapted to be locked to said plate. The plate10, is semi-circular in form and practically fits against the inner faceof the whip socket and is secured in place therein, as for instance bymeans of a pin or nail 12, ex-

tending through the adjacent walls of the plate and socket and a tongue13, at the lower end of the plate which passes through is extremelyintricate and difiicult to follow when it is hidden from View, as it iswhile covered up by the wall of the whip socket.

From the entrance opening 15, said slot has an upwardly extendingportion 16, terminating in a notch 17, extending toward the right.Slightly above the point of entrance 15,"the slot runs to the left as at18, then down as at 19, to a horizontal portion 20, which terminates ina downwardly extending and right angled portion 21, 21 In the horizontalportion 20, is a downwardly opening notch 22, and opposite a tongue 23,is

.an upwardly extending portion 24, which leads to another horizontalportion 25, con

taining offset portions 26, 27. Extending up from said horizontalportion 25, is another vertical extension 28, which terminates in ahorizontal portion 29, having vertically extending notches 30, 31, thatextend in opposite direction from said horizontal portion 29.

The pin orstud 11, may of course besecured in the whip stock in anydesired manner, as for instance it may be screwed therein, and projectsbeyond the face of the whip stock sufliciently to form a firm bearing onthe marginal edges of the irregular slot 14:, in the plate 10.

The whip is locked in place by inserting it into the socket, bringingthe pin or stud 11, down along the edge 0, of the plate 10, and thenturning it around toward the left, as viewed in the drawing, andbringing it up into the entrance 15, of the irregular slot 14. The pinmay then be moved through said slot into any one of the recesses thereofand I have shown the pin in the end of the horizontal ofiset portion 26.To detach the whip, the pin should be moved in the direction taken bythe arrows in Fig. 1. It is obvious that when said plate 10, is coveredby the wall of the whip socket, it is an exceedingly difficult matter totrace the direction which the pin should take in removing it from theirregular slot in view of the many turns and abutments with which itcomes in contact in moving about in the irregular slot. One knowing theshape of said slot .may, however, easily follow the same and quicklybring the pin to the entrance opening 15, after which the whip may bewithdrawn. For the guidance of the owner a mark D, is placed upon thewhip, which mark indicates, by reason of its position relative to theupper edge of the whip socket, the exact location of the in 11, in theirregular slot 14. WVith this guide before him the owner can morereadily locate the position of the pin and guide it out of the slot. Forhis further guidance, a card may be printed, bearing a facsimile of theslot in the plate, which card may be used by the owner to guide him inmoving the pin out of its locked position.

The edge C of the locking plate opposite the entrance 15, is straightand unbroken, so that the user may slide the pin 11, along this edgewhen he wishes to have the socket support the whip without locking it,the whip being then free to be withdrawn at any time, as for instancewhen he wishes to have the whip in readiness for use.

In the modified form shown in Fig. 4 the curved plate C is shown assecured to the whip stock B and the pin 11 secured in the wall of thewhip socket A so as to project into the socket or hollow thereof. Theirregular slot 14 of any suitable shape is formed in the plate C and theoperation of locking or unlocking the whip is substantially the same asthat of the preferred form.

I am aware that various alterations and modifications of this device arepossible without departing from the spirit of my invention, and I do nottherefore desire to limit myself to the exact form of construction andarragement shown and described.

I claim as new and desire to secure by Letters Patent:

1. A whip lock comprising in combination, a whip socket, a whip, a platehaving an irregular trackway therein and secured to one of said membersand a projection secured to the other of said members and adapted toseat in said irregular trackway of the plate to lock the whip in thesocket.

2. A whip lock comprising in combination, a whip socket, a whip, a plateof semicircular form secured to said whip socket and having an irregularslot formed therein, comprising vertical and horizontal ofiset portionsand an entrance opening, and a projection on the whip adapted to bemoved into said slot to lock the whip in the socket.

3. A whip lock comprising in combination, a whip socket, a whip, acurved plate secured in said whip socket and having a slot of irregularform comprising an entrance opening and a continuous slot having offsetnotches extending back therefrom, and a stud projecting from the whipand adapted to be inserted in said slot to lock the whip in the socket.

4. A whip lock comprising in combination, a whip socket, a whip, acurved plate secured in said whip socket and having a slot of irregularform comprising an entrance opening and a continuous slot having offsetnotches extending back therefrom, a stud projecting from the whip and.adapted to be inserted in said slot to lock the whip in the socket, anda mark upon said whip for determining the location of said pin in theslot.

In witness whereof I have hereunto subscribed my name at Chicago, Cookcounty, Illinois, this 16th day of May 1910.
